The Extech HD450 is a highly efficient Datalogging Heavy Duty Light Meter, featuring a rugged double molded housing and user-friendly interface for ease of reading in varying light conditions. Manufactured by Extech Instruments, this model offers a vast measurement range of up to 40,000Fc or 400,000 Lux, catered by its large backlit LCD display with a 40-segment bar graph. It supports extensive data capture, automatically storing up to 16,000 readings and manually storing up to 99, with options for min/max and data hold functions. The HD450 uses a precise silicon photo diode and spectral response filter for cosine and color corrected measurements. Its peak mode function can capture the highest reading over a ten-second interval, aiding in accurate light level assessment. Also included is a practical built-in USB port for PC interface. Used in excellent condition, this light meter has seen minimal use, retaining like-new operational status without significant cosmetic wear.
